A general formulation for computing spherical helioseismic sensitivity kernels while incorporating systematical effects
Jishnu Bhattacharya, Shravan M. Hanasoge, Katepalli R. Sreenivasan
As helioseismology matures and turns into a precision science, modeling finite-frequency, geometric and systematical effects is becoming increasingly important. Here we introduce a…
Validating time-distance helioseismic inversions for non-separable subsurface profiles of an average supergranule
Vedant Dhruv, Jishnu Bhattacharya, Shravan Hanasoge
Supergranules are divergent 30-Mm sized cellular flows observed everywhere at the solar photosphere. Their place in the hierarchy of convective structures and their origin remain p…
Iterative inversion of synthetic travel times successful at recovering sub-surface profiles of supergranular flows
Jishnu Bhattacharya, Shravan M. Hanasoge, Aaron C. Birch +1
We develop a helioseismic inversion algorithm that can be used to recover sub-surface vertical profiles of 2-dimensional supergranular flows from surface measurements of synthetic…
Finite-frequency sensitivity kernels in spherical geometry for time-distance helioseismology
Krishnendu Mandal, Jishnu Bhattacharya, Samrat Halder +1
The inference of internal properties of the Sun from surface measurements of wave travel times is the goal of time-distance helioseismology. A critical step toward the accurate int…
Frequency shifts of resonant modes of the Sun due to near-surface convective scattering
Jishnu Bhattacharya, Shravan. M. Hanasoge, H. M. Antia
Measurements of oscillation frequencies of the Sun and stars can provide important independent constraints on their internal structure and dynamics. Seismic models of these oscilla…
